Recently added mathematic functions, e.g. derivatives or integrals, expanded the functionality of MultiCon. Derivatives can be used for example in detecting changes in a measured process. Using derivatives as an incline of a measured value diagram, you can easily detect any changes within the process. Thanks to that, you can read any unwanted temperature decrease or the moment the temperature increase stops (e.g. the moment of furnace heating). Oftentimes, this is the signal to start some other process, to change the heating profile, or to simply register the time of the incident. Furthermore, the user can decide what level of change (rise/fall rate) should trigger a reaction from the controller.
